TD sra LUBQBICATING GREASE-CUP.

Application filed ugust 8, 1916. Seria1No.'113,7 "73.

To all whom it may concern:

Be it known that I, PERLEY F. Roen'ns, a citizen of the United States, residing at Bartlett, in the county of Carroll and State of New Hampshire, have invented certain new and useful Improvements in Lubricating Grease-Cups, of which the following is a specification.

This invention contemplates an improved lubricating grease cup and has as its primary object to provide a-device of this character wherein the cap of the cup will be adjustable for forcing grease out of the cup and wherein the said cap will be yieldably held at adjustment. 7

The invention has as a further object to provide an improved locking member arranged to coact with the cup shank for holding the cap of the cup at adjustment and wherein the said locking member can'be detached from the said shank only in a certain position of the locking member with respect to the shank so that the said locking member will not likely become lost or displaced.

And a still further object of the invention is to provide a cup of the above described character adapted for general application and use. r

Other and incidental objects-will appear as the description proceeds and in the drawings wherein I have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views:

7111 carrying outthe invention, the cup is providedwith a body 10 having an exter- I nally screw threaded stemll connected with the body by a reduced shank 12. The body 10 is internally formed preferably with a frustoconic al grease chamber 13 and adjacent its upper extremity, is externallyscrew threaded to adjustably receive a cap 14:. Surroundingthe stemf11, at the lower extremity of the shank 12 is an annular shoulder 15 confronted bya similar shoulder 16 at the upper extremity of the said shank, the shoulder 16 being formed by the lower endof the body 10 of the cup. Formed in the inner face of the shoulder 15 are a plu- 'ralit'y of radially extendinggrooves or sockets 17 quadrantly spaced about the shank .12 and which communicate at their inner extremities, with radial recesses 18 formed in ,thesaid shank. The cup ay, of course, be constructed any desired size and the shank 11 thereofrnay be varied in diameter as oocas on eydm n O that he 1 may be readilymounted by the said stem inactive position. Leading from the grease chamber 13 of the body 10' through the [stem and through thes h ank 12', a suitable channel .19 through which the grease from-the said h mbe mey'flo an in h s c nn t n, it will be observed; that the cap 14 may be adjusted upon the body 10 of the cup} for ford,

ing: th g ease out through the stem,- Arranged to hold the cap 14 at. adjust- I ment, is alockin'g; member or element shown in detail in Fig, 6' of thedrawings. This looking member .is preferably formed from pthe shank 12 of thecup and fit around the said shank in the manner illustrated particularly inFig. 5. The body 20isof an arc greater thanw a semi-circumference so that the distance betwee'n' the free ends of the .i-s id 7 body isless t n t d ameter of. the shank.12, Atene end, the body 201s cut "away to provide an] upwardly directed spring. tongue 21 terminating. at its outer V extremity in a shoulder 22 while the opposite end. of the. said body is cutaway to provide a shoulder 23. Projecting laterally from the body 20. adjacent the inner extreme ityof the tongue 21, is an upwardly directed arm 24c and from the said arm, the body 20 is bent longitudinally toward its outer ex- }provide. an upwardly bowed diacent its outer end, the body is bent or otherwise provided with a shoulder or rib 26. The arm 24 is arranged to extend longitudinally of the cap 1% as particularly seen in Figs. 2 and 3 of the drawings and is freely received by an eye or loop 27' carried bycthe cap.

It will now be observed that the body 20 is arranged to seat adjacent its inner extremity upon the upper face of the shoulder 15 with the spring 25 yieldably bearing between the shoulders 15 and 16 for urging the rib 26 to cooperate with the shoulder 15 and selectively engage withinthe sockets 17. At the same time, the spring tongue 21 will yieldably engage the shoulder 16 for holding the body 20 against lateral rocking movementbetween the shoulders 15 and 16 against the tension of the spring 25. Upon rotation of the cup 1 1, the body 20 of the the locking member to yieldably engage within one of the sockets 17 for holding the said cap at adjustment. Since the distance between the shoulders 22 and 23 of the body 20 of the locking member is less than the diameter of the shank 12 of the cup, the locking member will normally be held against displacement so that the said locking member will not, under normal conditions, become detached or lost.

However, 7 particular attention is now directed to the arrangement whereby the said locking member may be detached from the shank 12 when desired. To efiect this result, the shoulder 23 of the body 20 of the locking member is moved to a position opposite one of the recesses 18 in the shank. The arm 24: is then shifted to pivot the body 20 upon the said shoulder away from the shank 12, the shoulder 23 being thus caused to enter the said recess so that the shoulder 22 may then ride around the shank to free the locking member. In this connection, it will be observed that the distance between the inner extremity of one of the recesses 18 and the periphery of the shank 12 opposite the said recess is equal to the distance between the shoulders 22 and 23 so that when the shoulder 23 is disposed within one of the said recesses, as just above set forth, the shoulder 22 will freely ride around the shank so that the locking memr ber may thus be easily disconnected. The

locking member having a body rotatable locking member becoming accidentally displaced is reduced to a minimum.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
